Podcasting distributes multimedia files, such as audio or video programs, over the Internet using syndication feeds for playback on mobile devices and personal computers. Streaming refers to media that is consumed (heard or viewed) while being delivered. Streaming is more a property of the delivery system than the media itself. The distinction usually is applied to media distributed over computer networks. Podcasting, streaming, and other Internet-related technologies that send large files (e.g., audio, video, or graphics) have classroom applications. When used on the school network, they need to be evaluated for bandwidth consumption.
